' Patented il'uly 10, 19065 Application filed October 3,1904..-SeriaLNo. 227,018 1 1'0 all whont it nuty' concern:

in the county of Winnebago and State of W is.

consin, have invented eertain new and useful Improve nents inCmled-Wire-Fabric Machines, of which the following is a specifica tion.

I My inyention relates tomachines for cil-' ing and weaving wirev into afabric-such as employed, for instance, in the manufacture of wiremattresses; and the object of my invention is to produce a machine ofthischaracter which shall be efficient and reliablein operation, capableof automaticallycoiling' and weaving the wire, beginning with the wireon the reel and ending with its conver,

sion into the complete wire fabric.'

My machine is designed and adaptedto. perform all its operations withprecisionand reliability, with the result that the product thereof isperfect and without the waste that would result from imperfectcoilingeorwveaw ing at any point in the fabric, 'Moreoyer, my machinepossesses reat capacity, and the arrangement is such t at the capacitymay be increased'by increasing the number of coilers and weavingdevices, so thatlohemafchine may be provided with a plurality of angs ofcoiling and weaving devices, producing separate Wire fabrics, butoperating as a unit or as a single machine. Again, in my machine: Iprovide for the adjustment of the parts sothat wire'fabrics with coilsof different size or pitchmay be produced. Furthermore, I provide noveland eflicient mechanism, herein designated'as pattern-racks, whereby thecords which. are arranged at the sides of a Wire mattress to form theborders and which are also run intermediate the width of the mattressfor strengthening purposes may be Woven into the fabric automaticallyaccording .to any predetermined arrangement as provided for by thepatternracks.

The various features of utility and advantage of my machine will be madeapparent from the description hereinafter given.

In'the machine herein illustrated; as embodying my invention I havechosen to show four gangs of coiling and Weaving devices,

taneously produced;'-but itwill. beunderstood that my invention, exceptwhere specifying a plurality of such gangs, is not to be limitedthereto, but that the same may be embodied in a machine employing onecoiling and weaving device and producing asingle- Wire fabric.

Before proceeding with a detailed descrip-' tion of the construction andmodeof operation of my machine I will state the operation briefly, asfollows: Assuming that the wire fabric isto be composed of double wires,as

usual inmattress-springs, and following out the operation of a singlecoiling and weaving device, the two wires taken from the reels are fedby means of feed-rolls to a pair of coilers, where the wires are giventhe proper coiling, the size or diameter of the coil and the pitchthereof being dependent upon the size and pitch of the spiral of thecoilers.

' The wires as thus coiled are brought together as a single wire and arepassed through a knife or cutting device and also passed or run into aweaving-channel. After the two wires thus forming, in effect, a singlewire or strand are run into the weaving-channel a sufficient distancethe] knife operates to cut off the wires. In the running or extending ofthe wires in the weaving-channel the same are woven or interlocked withthe coils of a preceding wire, after which the completed coils areraised a sufiicient distance in the weaving-channel to enable the nextor running wire to be itself interwoven with the last com leted wire orstrand in the fabric.

It will be understood that the feeding action of the feed-rolls is notcontinuous, but intermittent, and the same is true of the operatiohsconnected with the performance of the functions of. the weaving-channel,inasmuch as it is evident that the coiling andadvancement of the wiremust terrupted until the last wire as been oper. ated upon in theweaving-channel and been raised to a proper position therein so as to beengaged by the next or running wire in the weaving operation. y

As is well known, the strengthening-cords and border-cords character,and it is therefore essential that the machine shall provide for ause orbe in arejrun in fabrics of this the running or.

consist 'simpl y of the ordinary strand of two or more wires, which areinserted in the same position occupied by the preceding strand or set ofwires insteadof being regularly coiled therewith, with the result thatthe number of wires in a strandismultiplied and the fabric therebystrengthened at such point. It is desirable that the border shall have aseries of these strengthening-cords" and that the cords intermediateshould have simply a double set of strands; but in the fabriccorresponding to what will become the middle line of a wire mattress itis desired that the strengthening-cord shall alternate with.the

usual strands. The construction andar rangementof my machine are suchthat these cords may be run or inserted in an automatic manner andaccording to any predetermined patternthat is to say, the number of thecords at any particular point or line,.as well as'the location thereoftransversely of the mg to any'pattern which he may adopt.

Itwill be understood that the machine produces a continuous wire fabric,which is preferably received upon suitable windingrolls, such fabric ofcourse containing the material for a number of wire mattresses, ac-.cording to the length thereof It will also be fabric, may be varied bythe operator accordunderstood that the fabric in such continu-- 5 oneroll contains the border-cords at intervals corresponding to adivision-line between the various mattresses, which are separated, asusual, by withdrawing the strand connecting the border-cords of twoadjacent mattresses in the roll or fabric.

From the brief description already given of the machine it will beunderstood that the same is capable of simultaneous y weaving aplurality of fabrics when gangs of coiling and weaving devices areemployed. It Wlll also be understood that the fabric may be of thedouble-wire variety, as is the most common in commercial fabrics of thiskind. onsequently in the description hereinafter given it will beassumed without any limitation that the fabric is of the double-wire type, and for convenience in description the machine, will be described asif it had only a single set of coiling and weaving devices instead ofthe four sets or gan s illustrated i l. the complete machine of therawings.

Now describing the machine in detail and referring particularly to Figs.1,2, 3, and 4,- such machine, as herein shown, comprises a mainlongitudinal frame 1, consisting of par all el longitudinallyextendmgbeams or strips, and also a side frame 2, allsupported in suitablemanner, as by the legs 3. Upon the front end of the machine a head 4,adapted. r2 5 to carry some of the operating parts of the machine, suchas the feedrolls and coilers, is arranged to reciprocate in a horizontalplane in a. manner and for a purpose hereinafter -1nade apparent.'Asshown in Figs.. 1. to 3 1 0 justable, to which end the lower roll isin-the and 13 and 14, thisreciprocat'ing headis provided with posts orbearing-guides in two pairs rising from opposite sides of the machine,having between them the bearings of two feed-roll shafts 6 and 7, thepurposeof which is to feed the wire which passes between them'from thereel to the coiler or coilers in advance thereof, ashereinzii'tereirplained. In the present instance the pressure-surfaceof'the upper roll is a shell or c l-.

inder 8ysecured to theshaft; but the roll might, if-desired, be'made inonepiece.

- 1t is desired .that one of the feed-rolls shall act on the wire with ayielding pressure-and.

also that such pressure or tension shall be adpresent instance made in anovel manner,

such roll belng, in effect, a band or ring 9 in casea single-Wire fabricis to be produced, or

in case a double-wire fabric, as in the present instance, a pairof'rings is provided, or a plur'alityof rings in case of a gang-machine;In

this connection it will-be borne in mind that in the machineillustratedfour gangs of coil mg and weaving devices are employed, in

which instance a series of eight of these rings arranged infour pairs isemployed. These rings surround or encircle the lower shaft'7 and arespaced to'properdistance by means of a series of distance-sleeves 10,also encircling the shaft 9, Fig; 13 and Figss15to 17.

1 Between each ring and. the shaft is interposed a coiled spring 11, theouter end of which is fastened to its ring 9 and the other orinner endto the shaft 7, in the present instance such connection being made bymeansof' keys 12, as illustrated in Fig. 13, As a result of thisarrangement and construction the motion of the shaft 7 is not directlycommu-.

nicated to the rings or roll proper, but indirectly thereto with ayielding pressure and, through the medium'ofthe springs, it being.

- understood that the feed-rolls should act on the wires in such amanneras to feed. them properly, but without flattening or crushing them 5 pThe rings or bands are arranged in pairs, one pair for each gang and onering for each wire, assuming that a double-wire fabric is theone to bewoven or produced bythe machine. In order to obtainthe accurateadjustment ofthe rings as regards the tensio'n or pressure against thewires, the rings are adapted to be adjusted independently of theirshaft, whose adjustment will be hereinafter explained, and to this endadjustable rollers '13 are arranged below the rings in such man ner as.to bear against the lower peripher es thereof, Each ringcooperates witha, pair of these rollers, ,which are mounted to'rotate in avertically-movable cradle 14, having a depending fulcrum-pin 15. Thefulcrum-pins ave bearing-points at their lower ends, and

I the pins of two companion cradles cooperate with and bear against acommontransverse pin 17 and for each fulcrum bar 16, which is sustainedor sup ported at the upper end of a sin 1e ivot-pin 17,1b'earing againstthe under si e t ereof at a point -midway of the. bearing poin-ts'of thefu crumpins.

The fulcrum-pin 15, as well as the pivot-.

pin 17,'are movable in vertical openings'or holes in the block 17 of thereciprocating head or frame of the machine. The pin 17 is arranged to bemoved with a yielding pressure, and to this end an operat1ng-handle'19 Iis mounted to turn freely upon a cross-shaft I brackets 21, secured tothe block 18. When i a plurality of gangs of coiling and weaving devices are em loyed, there is a corresponding number of t ese handles,one handle for each an of rings or bands.

As shown, each han le is'provided with a projection or arm 22, arrangedto bear, as shown, against the head of an adjusting: screw 23, whichscrews into the lower end ofa depending rod or pin 24. a This latter pinbears against the same hole or op'ening'asthe pin17; but instead ofbearing directly there- 20 having its end supported in dependingagaln'st or forming a part thereof a spring 25 is interposed betweentheir adjacent ends for cushioning purposes and to yield to differentvariations in the w res and prevent such vanations asto one wire fromaffect ng-the tensionof the other wire or wires.

From theforegoing description it will be I understood that the upwardmovement 'ofj' {the right-hand 'end' of .the handle, Fig. 13, will move,the arm 22. away from contact with,

fith'e adjListing-screw 23, with the result that "the cradle and itsroller, together withfthea-s" sociated p arts,will drop forward, therebyre-x 'lieving-its rings or bands from any pressure 1 or tension to whichthey had been'previously' subj-ected. By adjusting the screws 23 up ordown the degree ofpressure of the rollers '13 and the;conse uent tensionof the rings upon the wireswill e correspondingly adjusted I that is,increasedor decreased. Itwillbe' understood that the'handles' 19 arepivoted loosely upon the cross-shaft 20- in order that the tension orpressure adjusting mechanism for the several gangs may be independentlyadjusted. v As will be clearly understood from Fig, 13, an upwardadjustment of the cradles and the rollers 13 will-move or adjust thepressure or feed rings to a position eccentric of the drive-shaft 7.,and such rings will consequently bear it with an increased pressureocking-ba'r 26 is pivoted to, the reciprocatinghead or frame of themachine, with its lower the end arranged. to coeperate and engage withBy actuthe parts in the normal position illustrated in said figure.

The-shafts of the feed-rolls are both ad justable vertically in theirguide-frames, as

. vertically in the opening in obtained, V I

clearlyindicated in Figs. 13'and 14. Referring first to the upper roll,the shaft thereof is journaled at its ends in blocks 30, movable portsor guides in the reciprocating head and resting upon the upper ends oftwo parallel vertical strips 32, extending along the inner sides orwalls of the guides and passing through slots at their lower ends. Thesestrips 32 extend beyond the lower-end of the guides and are outwardlyflanged at their extreme ends'to fit upon the upper face of anadjusting-nut 33. This nut screws upon aplug 34, secured in an the lowerend of the guide-frame, with the result that when the nut 33 is adjustedvertically the journal boxes or blocks 30 are correspondingly adjustedin their guides, the ed osition To, oldthe journal-blocks 30infixedposition after the proper vertical adjustment is provide set-screws36, bearing against the v screwing through bridge-pieces 37, extendingacross and connectin' the 'tops of the guides.- The lower feed-roll isikewise, j ournaled at its ends inboxes' or blocks 38, which are movableor vertically adjustable between; the

strips 32, as indicated in Fig. 14. To the and in addition such tubularextension lowerendsof theseblocks are secured blocks, 39, provided withscrew-threaded tubular-ex: tensions 40, which are adapted to cooperatewith vertical adjusting rods or shafts 41;,

These shafts are provi ed withcollars 42, which bear upon brackets 43,depending from the guides, and the extreme lower ends thereof extendthrough the brackets and are provided with anan ular portion to receivea ey-wrench or the ike. ,By. rotating these adjusting-shafts in onedirection-' or the other the feedroll shaft 9 is correspondinglyadjusted vertically up ordown; as the case may e-i .As clearly indicated1n-'-Fig. 14,- the ad justing-shafts, as well as the tubular extensions40, extend through thehollow plug 34,

top-of such boxes or blocks and caused to pass through ustratedparticularly in Figs. 1, 3, 13, and 22, for the purpose a ofstraightening out any kinks or bends in the wire and also for properlydirecting the wires before their entrance between the rolls. As shown,each wire has its own individual guide, each consisting ofa strip orsubstantially rectangularblock 44, provided with a longitudinal channel,in which the wire lies and runs, together with an upper strip or block45, provided with alongitudinal rib or fin 46, adapted to enter'thechannel of'the lower bar and to rest upon the wire as it asses through;Bypreference each lower lock rests in a bracket '44, secured tothemachine-frame.

of these guides, I mount them all on a cross-piece or plate 47,which isn adjustably secured to the sides of the feedguides 31 as more clearlyindicated in .Figs. 1, 3, and 13. This plate has depending brackets 48,which are slotted to receive the bolts 49, secured in said guides 31.The, proper adjustment of the cross-piece or plate is obtained byadusting the set-screws 50 and then tightening up the b s. To this plateis secured a parallel plat or bar 51, arranged thereabove and adapted toreceive a series of These screws are adap'te'd to bear against the upperblock 45 of the wire-guides in order to regulate the position of suchupper block to the passing wire and also in order to take up wear.

Thewires as they pass-through the rolls are fed to the coilers, one'for.each wire, whereby the wires are given the proper coil according to thediameter and pitch of the particular coilers employed. Each coilercomprises a coiler proper, consisting of :1 cyl-- inder 53, having aspiral roove 54 cut on its periphery and of the 'itc' to be imparted'tothe wire, Fig. 23. T is coiler is incased in a shell 5 55, and suchshell and its coiler are held in proper relative position and such partsare-also held in fixed position in the ma chineby means of a pin 56,passing through a plate-57 on .the machine and extending radially.through the shell 55 and partially enter ing the coiler. Each coiler isheld against upward displacement by means of "a set-screw" 58, passingthrough across-piece59ofthe machine and bearing against the top surfaceof the coiler-shell. I

To extend the coils as maybe desired or re quired as they emerge formthe coilers, I provide a tension device, which-acts upon the coils as aresistance by destroyin the regularity of the spiral path to be taken bh coils after they leave the coilers; The purpose of thus extending thecoils is to provide for a uniform pitch for. two companion wires, sothat they will keep close together and run together in harmony. To thisend I employ a short cylinder 60, (as detailed in Fig. 22

' groove 61, which is c'onsiderablywidened or enlarged at its moutl162,which is placed ,adjacent the rearward end of thecoiler proper.This'teiision-cylinder is adapted to enter the rearward end ofthecoiler-shell and to cooperate with the coiler for the purposes named.

In one position of the tension cylinder ,60 its spiral groove forms aperfect c ntinuation of the spiral groove on the coiler, with the result that the coil as produced and to' be run into its weaving-channelcorresponds in diameter and pitch to the grooves of the coiler and toits diameter. Howeverpthis tension-- cylinder is rotarily adjustablefor. the purpose] of varying the pitch of the coils after leavingthefcoiler, and, as will be observed from an eX- amination ofFigs 13 and22 of the'drawin s,

a rotary movement o'f'the tension-cylinder,

will break the uniformity orcontinuity' of the'spira'l by causing thewire to press with some force against one side of the mouth. or

enlar ed end of the groove ;6'1 in the tension cylin er and therebyflatten or extend the coils accordingto the amount of this rotaryadjustment. I. For the purpose ofrotarily adjusting the tension-cylinderas described suitable means Tareemployed, and in the. present instance(see Figs. 1, 12, and 21) I provide the reduced end of each of suchcylinders'with. an. up-

wardly-projecting pin 63, whoseupper- 'end' passesloosely through anopening in atrans- Iversely-adjustable bracket 64, slidable in atransverse groove in the cross-piece 59..

shown inFigs. 13 'and 21, .tlieseadjustable brackets are all dovetailedin said groove, and

byoperatinganyparticularone of tl ethumbnuts It will .be understood thatit is preeach of them adapted tobe adjusted or shifted independently andtransversely by means of a thumbf-nut 65, screwing upon. the

transverse screw-rod Q6, having bearings at its ends in saidcrossfpiecaFigsai 1," 13, 21.

Each nut is arrangedto bear against apro j ectionon its bracket, withthe result that any v piece 73 of thereciprocating frame orhead.

oneof the "brackets may be shifted laterally ferred that thetenSiQH-cyIindersshaH have separate and independent adjustment and thatconsequentlythere are as many of the brackets and thumb-nuts as thereare coilers andtension-cylinders. j

The wires as coiled by two' companion coilers are fed" along twochannels or grooves 67,

formed on the-top surface of apl'ate 68 and converging at the forwardedges thereof.

This plate, which ispreferably of non-con,- ducting material, such asafiber, which is a non-conductor of electricity, extends trans-' verselyof the machine, as seen in Fig. 1, and isof course provided with as manyof said channels'as there are coilers, in the present instance havingeight of such channels arranged in four pairs, inasmuch as four gangs ofcoiling and weaving devices for producing at the ends of the convergingchannels or grooves 67, and the same are then threaded through aknife-block 69, a series of which is provided in the present machine,one for each pair of coilers, Fig. 30. Each knife or cutter-block has aforward cylindrical portion and a reduced rearward portion which is cutdown through a diameter to present a fiat horizontal cuttimt-surfaceover which the knifel70 passes. Ks seen in Fig. 13, the periphery orouter surface of the knife-block isspirally grooved fora portion of itsextent in order to receive the pair of wires which pass together theretofrom the coilers, and in order to forman opening through which such pairof wires shall emerge on the cutting-surface of the knife-block Isurround the lower half of the knife-block, or at least the rearwardportion thereof, with a semicircular band 71 ,whereby the opening 7 2 isprovided forthe wires, as indicated-in. Fig. 28. a

The series of knife-blocks is secured in fixed positionin suitablemanner, and in the present instance such blocks pass through openings ina cross-piece 73, and they are held or secured thereto by means of theset-screws 74, all as clearly-indicated in Figs. 25, '27,

and30. 1

Each knife-block is provided with a knife 70, which is moved at theproper predetermined time, with the result that the coiled wires arecutoff after a certain length thereof'has been fed'or run through theopening 72 to the weaving devices. In the present in stance the knives,which are flat plates pre :se'nting abutting, edge or corner totheknifeblocks, are secured in suitable manner to a transverse bar 75,arranged to slide in grooves formed in the upper portion of the cross(See Figs. 1, 13, 27, 28, and 30.) The knifebar is operatively connectedwith a trans-, verse plate 76,. adapted to slide transversely 'of themachine and to be'operated through connections with the'power or driving1nech-' anism,-. as hereinafter explained. As indicated in Figs. 25, 26,and 27, this plate 76 has its bearing in the lower portion of thecrosspiece 73 and the same is designed not only to operate thecutter-bar,,but also to operate a back-feed arm, as will-behereinafterdescribed. The operating connection between the cutter- -bar and theactuating-plate 76 consists in the present instance, Fig. 25, of a lever77, pivoted at its upper end to the cross-piece 73 and connected withone end of the cutter-bar by means of a link 78. The lower end of thelever is slotted in order to receive a pin 79. The object ofthe slot andof the connection is to enable. the feed-arm to be operated in advanceof the cutter-barin other words to cause the triggers or. feed-arms tobe first moved and the cutter-bar to be moved only near the lastmovement of the actuatinglate 76. As shown more particularly in Fig. 1,the left-hand end of the sliding plate is connected by a rod 80 with theend of an.

actuating-lever 81, pivoted on one of the side frames orbeams of themachine. The other'end of this actuating-lever is connected with asliding or reciprocating rod 82, extending transversely of the machineand operated by power mechanism, as hereinafter first-described strandand to take the same On. .thefront side of this actuatingplate and.

position.- y

In the present instance, and referring more particularly to Figs. 25 to31, the feed-arm is a pivoted lever or trigger 83, having a pe'culiarmovement in order to enable it to accomplish the purposes described.This-arm or trigger is secured at its lower end to a transverserock-shaft 84, which is' common toall of the arms or triggers employedin the (present gang-machine. This rock-shaft is,

supported at the rearward ends of the links 85, which are secured to atransverse shaft 86 suitably-journaled at its ends in the machine-.frame. The u per end of the arm or trig er voperatesin an projectsslightly above a slot or opening 87, extending in a transverse bed-,plate 88. or triggers in a normally forward position and to take uplost motion as indicated in Fig. 27,

The mechanism just described is employed for the purpose of giving thefeed armor trigger 83 the proper vertical movements; but in order toprovide for the forward and rearward movement of such arm I employsuitable mechanism for automatically sliding the plate 90, whose endsare movable in guides 100 in the machine-frame, as indicated in Figs. 25and 27. this reciprocation is brought about by connection with theactuating-plate 76 by suitable connections, as follows: The plateiso'peratively connected withthe upper ends of arms 101, which aresecured to a'rock-shaft 102. From this rock shaft projects forwardly anarm 103, whose extreme forward end is formed as pin 104, received andoperated by a cam-slot 105 at one end of the ac- In the present instancetuating-plate 76. It will be observed that a slight transverse-movementof this actuatinglate will move the cam-pin 104 in a vertica plane, asindicated by the dotted lines in Fig. 28, whereupon the shaft 102 willbe rocked and the plate or strip90 be thereby reciprocated forwardly andbackwardly on' its pivots. Inasmuchas the plate 90 is operativelyconnected with the arms or triggers,

forwardly and backward y.

The different mechanisms described in connection-with each back-feed armor trigger .combine to give the peculiar movement reuired-of the latterin order to act upon the orward end of the cut-off strand or set of'wires, and in Fig. 31 I have illustrated by dotted lines the course orpath of movement of the extreme u 'per end of each-trigger in each ofits cycle 0 movements, from which it will be seen that the firstmovement downwardly and then upwardly in a semicircle until it engagesback of the first coil of the strand adjacent the cutter, whereu on atthe next and forw'ard'movement of t e trigger" the latter will be corresondingly actuated the extreme forward end of the wire-will be drawnforwardly of. the opening 72 in the knife-block.

J The cycle of operation of the .parts illustrated in Figs. 25 to,31 isas follows: ,Assuming that the wires have just been run through thecoilers: and through the knifernechanisrn to the proper extent, thelever 81 is actuated, 12o' with the result that the plate 76 is shiftedtoward the right, Fig. 25, whereupon the stud 93 of the lever 92, whichis normally held in the position indicated in Fig. 26; by the tension ofthe s ring 106'acting on the rocke shaft 84, will e contacted by thestop-finger 96 and Will-be forced downwardly-by the curved contact faceor-surface' thereof, with the result that the lever92 will be rocked andsuch rocking movement mmmunicated to .the rock-shaft 84 and feed-arm 83, which parts will now assume the position indicated in dotted lines inFig.'27. When the actuating-plate 76 is moved to the right, asdescribed, the cam-pin 104 will ride upwardly in its cam-slot 105, withthe result that the plate or strip 90, to which the trigger is alsoconnected, will be permitted to move rearw.ardlythat is, to the left inFigs. 27 and 28.until the parts assume the relative positionshown by thedotted lines -in Fig. 2-8. Toward the end of the stroke of theactuating-plate 76 the knife mechanism will be actuated, inasmuch asbythis time the stud 'or pinj7 9 Willhave traversed the slot in the lever77 and have moved its lower end to the right,

Fig. 25, thereby moving the cutter-bar in the same direction andsevering the strands or set of wires. Upon the return movement of theactuating-plate 76 the knives will be restored to normal position, andthe feed-arm or trigger, which has already engaged behind the first'coil of the severed strand, as indicated in Fig. 30, will moveforwardly and draw the ends'of such strand forwardly and awayfrom theopening 72 in the cutter-block, so that the next strand orv set of wiresas they emerge from the knife mechanism. will be properly run togetherwith the first strand as a cord. In-this return movement of theactuating-plate 75 the stud 93'ofthe lever 92 will not be aifectedby the'stop-finger, which will flip by such stud as such actuating-platereturns to said normal position. In this connection it will beunderstood that the feedarm or trigger, although continuously operating,is effective only when a cord is to be run, at which time the coil isnot raised by the weaving-devices, but left inthe path of movement ofsuch trigger; At other timesthat is, when a'cord is not to be run-thecoil or wire is raised by the weaving devices out of reach of thefed-arrnortrigger.

" For the purpose of brin'gingthe ends of the strands or sets ofwires toa proper position at their forward ends, so that the wires may properlyinterweave, I provide for moving or reciprocating the entire head 4,which is so mounted asto-have a slight reciprocation'on the main endframe 1, this reciprocation being substantially one-half-the pitch ofthe 0011 being run, so that-the upper helix of the 7 running coil willinterweave with the; lower helix of the preceding coil. In thepres'entinstance and referring more particularly to Figs. 13 and 14 thereciprocating head lis mounted to slide upon said mainframe 1 and isoperatively connected with the power or drive mechanism in suitable;manner. As shown this is accomplished by means of a transverse shaft.107, journaled in the mainframe and providedwith similar pinions 108,arranged "to mesh. with horizontal racks 109 on each side of themachine. The racks are carried by the reciprocating head, one end of theracks being connected with the lower end of. depending pins or bolts1.10 and the other ends being mounted to slide in openings in the otherthe entire reciprocating head is correspondingly moved. Asindicated inFig. 4,

the rock-shaft 107 is-provided with a crank.

by means of a rod 112, with another rockshaft 113, extendingtransversely ofuthe machine and actuated by the power or drivingmechanism in a manner hereinafter explained. It will be understood thatthis reciprocating head carries all of the operating parts connectedwith the coiling and cutting oif of'the wirc ,-and it will also beunderstood that the reciprocations of such head are properly timed inorder to cooperate with the movements of theweaving devices.

. From the foregoing. description it is obvi- .ous that the head will sopresent a running coil or wire that the same will properly interweavewith the preceding wire or OOll.

After ,the wires have been coiled. and

passed throughthe cutting mechanism they are delivered to the weavingdevices or mechamsm, where they are'woven or lnterlocked in order toform a complete coiled fabric.

The weaving mechanism is arranged in advance of the coiler and knifemechanism and in alinement therewith. As shown in the drawings,particularly in Figs. 1, 4, 5, 13, 18, 19, and 20, such weavingmechanismcon sists of aweaving-channel, with which 00- operates a series ofmovable elements adapted to act upon the coiled wires in-order to bringabout the desired weavingthereof. As shown, the weaving-channel iscomposed of two longitudinal strips or plates 11-1 and 115, ext-endingparallel to each other and having outwardly-directed flanges at theirupper ends. These plates are lined on their inner adjacentfaces withstrips 116 of brass orthe like, Figs. 18 to 21, in order to preventmagnetizationby electromagnet 117, occupying the lower portion of thechannel and constituting, in effect,- the bottom of the channel.
